Honda CR-V: Exhaust Emissions Controls

The exhaust emissions controls
include three systems: PGM-FI,
ignition timing control, and three
way catalytic converter. These three
systems work together to control the
engine’s combustion and minimize
the amount of HC, CO, and NOx that
comes out the tailpipe. The exhaust
emissions control systems are
separate from the crankcase and
evaporative emissions control
systems.

PGM-FI System

The PGM-FI system uses sequential
multiport fuel injection.

It has three subsystems: air intake,
engine control, and fuel control. The
powertrain control module (PCM)
uses various sensors to determine
how much air is going into the
engine. It then controls how much
fuel to inject under all operating
conditions.

Ignition Timing Control System

This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.

ThreeWay Catalytic Converter

The three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO2), nitrogen
(N2), and water vapor.
